KNOCKDOWN vIsE.

Application led May 27, 1913.

To all whom it may concern.'

Be it known that I, ADOLPH L. DE LEEUW, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Knockdown Vise, of which the following specification is a full disclosure.

This invention deals with an improved vise and it is concerned with certain struc-.

tural characteristics enhancing the serviceability of vises, and also it proposes features especially adapting vises for use in connection with machine tools.

One object within the contemplation of this invention is to create a vise-structure adapted to fill the office of an auxiliary attachment for machine tools and well adapted to be bolted to the table or carriage of such machine tool to hold the work very firmly, while at the same time occupying no more space than is necessary.

Another object is to render available a simple and durable vise embodying features for automatically drawing the work firmly onto the supporting surface whenever the jaws are brought into clamping relation with said work, so as not only to clamp the sides of the work, but also hold the same firmly onto its underlying supporting surface, thus mounting it as rigidly as possible on the table of the machine tool.

Another object is to devise a vise of a built up nature and such that its component parts may be shipped or kept in a tool box, and assembled very quickly for immediate use on the table of a machine tool, and further to design the same so that its capacity `may be greatly extended by the use of very few additional parts.

Other obj ects will be in part Obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts, and in the relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have Specification of Letters Patent.

and in such drawings, like characters of reference denote corresponding parts throughout all the views, of which v d Figure l is a top plan view showingthe vise assembled and illustrating various characteristic features thereof. Fig. 2 is a section taken through line 2*2 of Fig. l, showing further details of the construction, and illustrating the wedge-like moving jawpiece. Fig. 3 isa transverse section taken through line 3-3, of Fig. l, showing how the rails of the vise are clamped at their distant ends to the table of the machine tool. Fig. 4 is a section through line 4 4 of Fig. l, showing the follower which interlocks at successive stations to the rails and provides means for forcing the follow-jaw against the work. Fig. 5 is a section through line 5-5 of Fig. l, looking toward the clamping face of the follow-jaw, parts being broken away to illustrate the structure providing downward play of the jaw-piece under clamping pressures. Fig. 6 is a section through line 6-6 of Fig. l, showing the means whereby the fixed jaw is clamped to the rails.

Continuing now by way of a more detailed description, it may be noted that preferably this vise is formed of a head serving also as a iixed jaw and adapted to be clamped directly to the table; a pair of rails detachably secured to the head providing means for clamping their remote extremities to the table at any desired point, and also followjaw Construction adapted to be secured at any station to the rails, and providing means for applying clamping pressures to advance the same into clamping relation with the work.

The fixed j aw is indicated by A, and consists of an elongated slotted body portion l, preferably providing slotted wings 2 and 3 extending coincidentally with the longitudinal center-line of the vise, and adapted to receive the Shanks of bolts 4 and 5, which secure in place a fin 6 adapted to be snugly received in one of the T-slots of the table. This construction, being detachable and interchangeable enables a 1in of any proportion to be used to meet any given size of slot and it is to be observed that the slotted wings 2 and 3 are low so that the head of the bolt does not rise above the upper surface of the rails, and

n the same.

thus come in contact with *the work. Extending outwardly from the ends of the fixed jaw A are also similar slotted wings 7 and 8, which are adapted to receive bolts taking into slots of the table whereby-the fixed jaw may be clamped securely onto the table; the n thus maintaining the vise in parallelism with the slots, as will be understood. It is noteworthy that the wings 7 and 8 are preferably counterparts of wings 2 and 3, so that the above mentioned relation may be interchanged, if desired; a longer n being in this instance employed and the wings 2 and 3 being now used for clamping the xed jaw on to thetable. Should it be desired to have the work bear directly on the table, the jaw-piece may be constructed to overhang 'the wing2, or the latter may be dispensed with. This fixed jaw A preferably provides a` self-adjusting jaw-piece 9 having a-scored or roughened clamping face 10, and a vdownwardly and outwardly inclinedface 11, which is backed against a similarly-sloping face of the body portion 1 of the fixed jaw. Normally, this self-adj usting jaw-piece is held slightly elevated by means of springs 12 seated in sockets providedby an underlying portion of the fixed jaw and pressing upwardly against the under surface of the self-adjusting jaw-piece 10. The latter is held in place by means of a ypair of bolts 13 which have their ends screw-'threaded into the self-adjusting jawpiece, and .are caused Ato draw the same against the sloping face of the lixed jaw by meansof expansible springs 14.

The rails B extend in parallelism from the fixed-jaw, to which they are preferably secured.v This is accomplished by cutting away -the ends of the rails to provide a narrow web ,1:5 terminating in a head 16 and received inkv acorresponding slot extending upwardly from the under side of the fixed head A.. EHollow-headed set-screws 17 engage the webs 15 and holdthe parts vrigidly together. The opposing longitudinal'faces or sides of the rails are ,provided with slots 18 lfor positioning the follow-jaw and guiding the follower, and also for receiving and accommodating the straddle bar which clamps the rails-downto thebed yat any desired point. This will now `be described.

The straddle-bar C consists of a Vmember havingan intermediate aperture 19 adapted to receive a bolt 2O adapted to engage a T-slot of thesupporting table whereby the straddle bar may be clamped down toward The ends of the straddle bar C provide slightly inclined clamping faces 21 adapted to rest upon the similarly inclined bottom faces of the slots 18 in ythesidesfof the rails B. This construction eliminates a spreading of the frails under themovement of the s'traddle-bar C.

The'follow-j aw D consists'of a body portion 22 adapted to ride upon the upper surface of the rails B and having a depending intermediate portion 23 from which horizontally extendcircular segments 24 adapted to enter the slots 18 of the rails. The outer circular contoured segments 24 are inscribed about `a center 25, so that the point 25 will be kept in coincidence with the central longitudinal plane of the vise, while yet permitting the follow-j aw to swivel about the point 25. This follow-j aw carries a self-adjusting jaw-,piece 26 mounted andconstructedthereon inthe same way that the similar piece 10 is arranged on the fixed jaw. It will be y noted 'that the follow-jaw D is freely movable onthe rails B and is capable of swiveling about the vertical axis 25 so-that lit may be brought into contact with any work-that maybe laidon the rails B against the fixed jaw. The means for-exertingclamping pres sures will now ybe described.

The follower E consists of a'vmember having side wings 27 extending lover the -rails B and providing abutment faces 28 angled. at about 30o to the perpendicular, which -in this instance will Abring the line of pressure normal lto such faces. The other side 29 'will preferably extend Aparallel withthe said line, or L'in other words, at right angles with the abutment face 28.l Counterpart notches 30 are spaced along the top face of the rails B so that the wings 27 may -be -received Vin said notches at any desired station. vAn intermediate portion 31 extends downwardly from the follower E between .the rails and provides forwardly 4positioned feet 32 that enter the slots in the yrails and bear against' the top faces of said slots to resist overturning ofthe follower'Eunder clamping -pressures. Extending-through the centerline'of the follower E is a suitable clamp screw133 which at its forward end bears against a segment lblock 34 secured to thefollow-jaw l) and having its periphery inscribed about the center 25 so that in any' angled position ofthe follow-j aw D the clamp screw 33 `will exert pressure ldirectly throughthe center 25. is welladaptedv to achieve the objects and advantages enumerated inttheforegoing and vconstitutes a very simplefand serviceable structure. By reason ofthe self-adjusting j aw piece, any work clamped Ybetweengthe Jaws will be drawn tightly'under vthe Lrails B andthus maintained against any possible vibration. At vthe'same time, by reason of the capacity forl swiveling vpossessed bythe follow-j aw, angled work -maybe clamped as well as straight work. The whole Vmay -be assembled with ease 'and it `may bestored away in the Atool box by occupying little room, and since the rails may -be lmade of any length, l,the vise has almost vunlimited capacity.

Having revealed my invention, I claim as Tt will thus be seen that this inventionr new and desire to secure by Letters Patent of the United States l. A knock-down vise of the nature disclosed combining a xed jaw having means for clamping it to a table, a pair of rails detachably connected to and extending in parallelism from said xed jaw and spaced apart, a follow-jaw riding on said rails, a follower adapted to interlock at one of a series of stations with said rails and having a clamping screw extending into abutment with the follow-jaw to force the same to` ward the fixed j aw, and means for clamping the rails to a table.
